Pre-Assignment Details

Significant events and approaches for the overall study
following participant enrollment, but prior to group assignment

Solicited symptoms were collected for 3730 and 3740 subjects instead of the 3727 and 3739 subjects who were randomized in the study in the Cervarix and the Havrix groups, respectively. These 4 sujects received both vaccines and were included in the denominator of both arm based on the actual vaccine type administered.

Reporting Groups

Description

Cervarix Group

Subjects received 3 doses of Cervarix vaccine at study Months 0, 1 and 6. All the vaccine doses were administered intramuscularly in the deltoid region of the non-dominant arm.

Havrix Group

Subjects received 3 doses of Havrix vaccine at study Months 0, 1 and 6. All the vaccine doses were administered intramuscularly in the deltoid region of the non-dominant arm.

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

The According-To-Protocol (ATP) cohort for efficacy included subjects with efficacy data available, who received 3 doses of vaccine, who were HPV DNA- for the corresponding type at enrollment and at the time of administration of the 3rd dose (Month 6) and who did not have a biopsy or treatment during the vaccination phase (prior to the Month 6).

Limitations of the study, such as early termination leading to small numbers of participants
analyzed and technical problems with measurement leading to unreliable or uninterpretable data

The following analysis "occurence of histopathologically confirmed CIN2+ cases associated with HPV16 or HPV18 infection was not performed, in accordance with the Statistical Analysis Plan submitted to the FDA.

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts
the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is less than or equal to 60 days.
The sponsor cannot require changes to the communication and cannot extend the embargo.

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is more than 60 days but less than
or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.

Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.

Restriction Description:
GSK agreements may vary with individual investigators, but will not prohibit any investigator from publishing. GSK supports the publication of results from all centers of a multi-center trial but requests that reports based on single-site data not precede the primary publication of the entire clinical trial.
